Add support for command and subcommand aliases

Feature Request: Add support for command and subcommand aliases

As discussed in #132 (comment), there's a need for official alias support in Typer.

Examples needed:

• Command aliases: list → ls, remove → rm
• Subcommand aliases: versions → ver → v, documents → docs

Current workaround:

@app.command("list")
@app.command("ls", hidden=True)  # Hidden alias

Requested feature:

Official alias support that doesn't clutter help output and provides a clean API for creating command shortcuts.

This would bring Typer in line with other popular CLI tools that support aliases natively.

@app.command("list",aliases=[]) maybe is a better way

@app.command("list", "ls") would be another way I'd expect the interface to allow me to specify aliases, just like how you can do that for option aliases as in typer.Option("--silent", "--quite").

I found this #132 (comment) It would be great if it were a built-in feature.

In the help output, I'd expect the possible commands to be comma-separated, similar to how it is usually done in the OPTIONS section of man pages (example):

╭─ Commands ──────────────────────────────────────────────────────────────╮
│ ls, list                        List the things.                        │

Which means that it'd make sense to go with an "all options are equal" approach (as @AlejandroFrias suggested), as this would kind of mirror what is shown in the help output: @app.command("ls", "list")

If we want to be able to hide aliases, I'd suggest something like: @app.command("ls", "list", hidden_aliases=["secretlist"]).

Sure, but please note that we're not accepting vibe-coded PRs 😉

Haha, understood! I’ll keep it clean — no vibe-coding here 😄

@svlandeg I added a PR, would you please check it?
